CreateJS extension - will it install in FlashCC?

I get an error if I try to install Toolkit for CreateJS (see attached screengrab).

As FlashCC is version 13 I suspect this extension will only install in Flash CS6. I wonder if this is now built in to CC somewhere. If so, where?

As there is no Flash CS6 download available in Creative Cloud, I would hope I can install it for CC - but I don't know how.

I'm trying to replicate the export FLA file from InDesign as shown in Terry White's tutorial here: http://tv.adobe.com/watch/creative-suite-podcast-designers/go-from-ind esign-cs-55-to-html-5/

Or is there another way of doing this now, with another of the CC applications?

thanks
